Under-Ice Phytoplankton Blooms in the Central Arctic Ocean: Insights From the First Biogeochemical IAOOS Platform Drift in 2017
(Journal article; Peer reviewed, 2020)In April 2017, the first Ice Atmosphere Arctic Ocean Observing System (IAOOS) platform equipped with biogeochemical sensors was deployed near the North Pole. Over the next 8 months it meandered southward with the ice, ... -
Underlying event properties in pp collisions at √s = 13 TeV
(Journal article; Peer reviewed, 2020)This article reports measurements characterizing the Underlying Event (UE) associated with hard scatterings at midrapidity (|η| < 0.8) in pp collisions at √s = 13 TeV. The hard scatterings are identified by the leading ... -
Understanding climate change impacts on biome and plant distributions in the Andes: Challenges and opportunities
(Journal article; Peer reviewed, 2022)Aim: Climate change is expected to impact mountain biodiversity by shifting species ranges and the biomes they shape. The extent and regional variation in these impacts are still poorly understood, particularly in the ... -
Understanding differences in North Atlantic poleward ocean heat transport and its variability in global climate models
(Journal article; Peer reviewed, 2021)The ocean heat transport from the North Atlantic to the Barents Sea impacts the sea ice extent and the energy budget of the Arctic. The analyzed climate models from the fifth (CMIP5) and sixth Coupled Model Intercomparison ... -
Understanding learner behaviour in online courses with Bayesian modelling and time series characterisation
(Journal article; Peer reviewed, 2021)The intrinsic temporality of learning demands the adoption of methodologies capable of exploiting time-series information. In this study we leverage the sequence data framework and show how data-driven analysis of temporal ... -
Understanding of European Cold Extremes, Sudden Stratospheric Warming, and Siberian Snow Accumulation in the Winter of 2017/18
(Peer reviewed; Journal article, 2020)It is unclear whether the Eurasian snow plays a role in the tropospheric driving of sudden stratospheric warming (SSW). The major SSW event of February 2018 is analyzed using reanalysis datasets. Characterized by predominant ... -
Understanding the correlation between (g − 2) μ and μ → eγ in the MSSM
(Peer reviewed; Journal article, 2014-08)The supersymmetric contributions to the muon anomalous magnetic moment a μ and to the decay μ → eγ are given by very similar Feynman diagrams. Previous works reported correlations in specific scenarios, in particular if a ... -
Understanding the dynamics of recent Norwegian extreme weather events and their influence on energy production
(Master thesis, 2021-08-05)The growing frequency and severity of extreme weather events in the Northern Hemisphere has prompted a lot of research being done on their origin and physical mechanisms. Both simplified and complex approaches have been ... -
Understanding the occurrence and fate of microplastics in coastal Arctic ecosystems: The case of surface waters, sediments and walrus (Odobenus rosmarus)
(Journal article; Peer reviewed, 2021)The Arctic ecosystem receives contaminants transported through complex environmental pathways – such as atmospheric, riverine and oceanographic transport, as well as local infrastructure. A holistic approach is required ... -
Understanding the role of organic matter cycling for the spatio-temporal structure of PCBs in the North Sea
(Journal article; Peer reviewed, 2020)Using the North Sea as a case scenario, a combined three-dimensional hydrodynamic-biogeochemical-pollutant model was applied for simulating the seasonal variability of the distribution of hydrophobic chemical pollutants ... -
Undersøkelse av effekten av katalysatorer og støttematerialer på omdanningen av lignin til LtL-biooljer ved forskjellige betingelser
(Master thesis, 2014-12-19)Verdens petroleumsforbruk har skutt i været de siste tiårene, og man inser at ressursene holder på å gå tom. Dette har tvunget oss til å begynne å tenke på alternative måter å produsere energi og drivstoff på. Lignocellulosisk ... -
Undersøkelse av reaksjonsmekanismer for OMEbrennstoff for bruk til implementering i 3D-CFD simulering av forbrenning
(Master thesis, 2019-06-28)Oxymetylene etere (OME) er brennstoff som brenner så og si uten utslipp av sot. Disse syntetisk skapte brennstoffene kan spille en viktig rolle i diesel miksen en dag, og kanskje til og med et surrogat for diesel. Brennstoffet ... -
Undersøkelse og optimalisering av krysskoblingsmetatese ved hjelp av statistisk eksperimentelt design og multivariat regresjon
(Master thesis, 2008-06-03)Kryssmetatese er en metode for syntetisering av høyere olefiner fra enkle terminale alkener. Utviklingen av nye katalysatorer har ført til et utvidet bruksområde for denne metoden. Kryssmetatese kan gi tre par produkter, ... -
